For flats I'd suggest steering clear of Chromes. After trying them several times, I find that the G string never quite breaks in like the rest and sounds out of place.
I've played the Fender 9050s before. I like the string but they do have a particularly high tension (same as the LaBella James Jamersons and the Rotosound Jazz flats) that you might not like. I don't mind it but I recommend a light touch when you play them. I switched back to them for awhile and ended up giving myself blood blisters from playing too hard.
The Rotosound Trubass 88s, I really like them a lot. Clear and articulate and they never die! They have their own particular sound when you dig in though which, to my ears sounds kind of plasticy. I have a sound clip of them on a P bass if you wanna hear it.
You also might want to try the GHS Precision flats. They're dirt cheap and sound and play nicely.
I've also heard good things about the DR HiBeam flat but I've yet to try.
If you wouldn't mind shooting a sound clips of the Rotos my way, that'd be sweet. And I actually do prefer higher tension strings; nothing extreme but stuff like the TI flats are just way too floppy for me.
